Style of the Milgauss

The Milgauss has remained faithful to its scientific heritage and unique identity as it has evolved. With its clean lines and evocative orange seconds hand, shaped like a lightning bolt to echo the original model, the Milgauss is recognisable at a glance.

An EfficientShielding System

Function of the Milgauss

The first innovation at the heart of the Milgauss' resistance to magnetic interference is the shield inside the Oyster case. Made of ferromagnetic alloys selected by Rolex, it surrounds and protects the movement.
The symbol for magnetic flux density – the capital letter 'B' with an arrow – is engraved in this magnetic shield, but only Rolex-certified watchmakers will ever see it.

Paramagnetic Components

Function of the Milgauss

Several key components in the movement of the new‑generation Milgauss are made of innovative paramagnetic materials, including the blue Parachrom hairspring. They were developed and are made in-house with advanced technology thanks to Rolex’s unique command of the whole watchmaking process.

History ofthe Milgauss

Spirit of the Milgauss

The reliability and precision of an ordinary mechanical watch can be affected by a magnetic field of 50 to 100 gauss. But many scientists are exposed to much higher magnetic fields during the course of their work. Rolex’s solution was the Milgauss, created in 1956, the first watch of its kind. Hence the name of the watch, mille being French for thousand.

THE ORIGINS
1956

The Largest Laboratory, The Tiniest Particle

Spirit of the Milgauss

The European Organization for Nuclear Research (CERN), the world's pre-eminent particle physics laboratory, is at the cutting edge of scientific research into the fundamental secrets of the universe.

It hosts the world's highest-energy particle accelerator. In the 1950s, CERN was also one of the first scientific institutions to confirm that the Milgauss watch could indeed resist magnetic fields of up to 1,000 gauss.

904LStainless Steel

Features

Rolex uses 904L stainless steel for its steel watch cases. 904L is mainly used in the high technology, aerospace and chemical industries, where maximum resistance to corrosion is essential. A superalloy, 904L is extremely resistant and highly polishable. It maintains its beauty even in the harshest environments. 904L steel also provides a perfect complement to the precious metals used by Rolex.

The Parachrom Hairspring

Features

In a mechanical watch, the oscillator is the guardian of time. Conventional oscillator hairsprings are made of ferromagnetic alloys, leaving them vulnerable to magnetic fields, temperature variations and shocks that interfere with their precision. After years of research, Rolex created the blue Parachrom hairspring, which is finer than a human hair.

Crafted from a highly stable paramagnetic alloy that includes niobium and zirconium, it is insensitive to magnetic fields and up to 10 times more resistant to shocks. Historically, the unique blue color of the hairspring has been a sign of prestige reserved for only the most accurate timepieces.

Oyster Bracelet

Features

The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection.

Green sapphire crystal

green • sap • phire

A unique watch crystal in green sapphire developed in 2007 by Rolex.

Scratchproof, fade-proof and available exclusively on the Milgauss.

Its light green shade, tinted throughout the entire crystal, turns nearly luminescent at the bevelled edges.

The result of a secret process that required years of development to master and takes weeks to produce.

Not patented, as it is so difficult to make that no one else would even venture to try.

The Rolex Way.

3131 Movement

Features

The Milgauss is equipped with calibre 3131, a self-winding mechanical movement entirely developed and manufactured by Rolex. It incorporates state-of-the-art technologies patented by the brand that ensure exceptional resistance to magnetic fields.

Like all Rolex Perpetual movements, the 3131 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.

Certified Swiss Chronometer

Features

The four simple words Superlative Chronometer Officially Certified on a Rolex watch dial mean that the very movement inside the timepiece has endured 15 days and nights of testing by COSC (Contrôle Officiel Suisse des Chronomètres – Swiss Official Chronometer Testing Institute), an independent not-for-profit association. To receive COSC certification as a Swiss chronometer, a watch must demonstrate extreme precision in a variety of positions and temperatures. Rolex is unique in the industry: this is the standard level of quality required of every Rolex wristwatch movement.
